IMPROVEMENT IN COFFEE-POTS.

fittt fidgttuls ttitttth tutti the haters ttzztmt an muting wt to thetime.

Be it known that LJONATHAN'G. DYER, of the city of Chicago, in thecounty of Cook, and State of Illinois, have invented'a'nen and usefulApparatus for Making Coifee and Tea; and hereby declare that thefollowing is afull, clear, and exact description of the construction andoperation of the same, reference being had to tlie annexed drawings,making apart of'this specification, in which i i i Figure 1 is aperspective view,

Figui-e'Z, section, I

, rig r p Figure '5, perspective view of strainer. 1 r r Thiscofi'ee-pot is ma'jle of tin or other suitable metal, of any convenientsize or shape, having soldered around its interior, about'o ne-third ofits height above bottom, a circularconcaveplate, b, o f tin, (or othersuitable inetalQ) havingjan aperture cut in the centre, large enough toadmit'a cup or straineryiB, which is to contain the coii'ee or tea. Theconcave plate entirely closes the space below it when the strainer B isplaced therein; There isan opening through the concave-plate,,underthespout of pot, but closed with a. hinged valve, d, designed to allowegress of the infusion.- The strainer B is from two and a half inches tofour inches deep,- andabout-same diameter, in shape a cylinder; withperforated sides, and madeof tin, the perforation ceasing at thedistance of, say, one fourthfo'f' an ineli from the 'bottom of strainer.The perforations maybe onefortiet-h'of an inch in dia, eter, or less ormore, according to coarseness of cofi'ee. The strainer has a movablecover, and there isaIso-a wire, from seven to ten inches in length,serving as, a handle, soldered to side of cup or strainer, (at c) andreaching "aboire the cover of the c ofiee or tea-pot, through a hole cutfor that purpose iirthe edge of covcrg 'and terminating infa handle orbutton, o. The strainciflon its insertion-into the opening in th 'eplate Zyrcsts, by its rim, in the same, and should reach to aboutone-fourthjof an iuch'of the bottom of the pot. To four points on thesides of the opening just described, arefastened wires, Us Zm, which,rising from thence, parallel'to each other, are soldered to the edge, ofopening of pot, and serve as guides for insertion of the strainerin'platelb. The'pot'is fitted with a-l1inged cover over the spoutf. p

The operation of this apparatus is as tollowsi 'lhe lowerchamber of potis half filled with water, and when boiling, the strainer :containing'cofl ee or tea, isgplaced in the aperture of plate 6, entirely closinglower chamber 1;, and preventing, in a great degree, the steam andstrength ofthe tea or'coti'ee from escaping. Most of what escapes fromthe lower chamber is retained-and condensed in the upper part of thepot, falling condensed back into hollow of plate, and intodo werchamber. Before pouring the codes out, the strainer should be taken out,and :1 suflicient quantity of hdt water poured into the. pot.

The advantagesof this apparatus are that, -first,'it savesone-thirdofthe usual alnonnt of codes or tea ordinarily used; second,the cofieepr tea. thus made is free from sediment; third, it isstronger, .by one-third, thanicofiee of ordinary make; fourth, itprecludes the necessityot' clarifying the coffee by means of eggs andegg-shells, 8:0. I i

What I claim as my invention, and desire to secure by Letters Patent,isr 1. Ina coffee or tea-pot, the combination of the imperforatedivision-plate 5, the vessel or receptacle B, with the handle a, and thesupporting andguiding-wires, all constructed and arranged substantiallyas shown. and described. 7 I p 2. .Thcralve d, in'combination with thedivision-plate b, as and for the purpose set forth.
